1. An associative mist control material comprising:
a mixture of polymers each having:
at least one non-associative chain, said non-associative chain being selected to confer solubility to the polymer in a particular medium such that the medium and the mist control material remain as a homogeneous single phase during storage and transport;
a plurality of associative groups disposed on at least one end of each of said non-associative chains, wherein the associative groups are selected such that the polymer does not self-associate, and wherein a plurality of associative groups separate each of said non-associative chains; and
wherein the associative groups of said polymers reversibly associate with an association strength less than that of a covalent bond to form supramolecules designed to prevent misting of the medium.
